The Tazer JL is great programmer tool for JL owners who want to have the most control over their Jeep’s settings, by boasting an impressive long list of features.

Installation is a simple 2 steps – a bypass module plugs in above the OBD2 connector and the Tazer JL itself plugs into the OBD2 connector.

There are two sets of features – those that program the vehicle to accommodate modifications made to the Jeep (or tweak settings), and the “live” features that run only when the Tazer JL remains plugged in.
